Distinguish between design, constructive substantiation and drawing work and record the collaboration.
A construction plan requires different types of work
A new layout must suit your wishes, building and relevant rules. The plan must also be constructively substantiated and recorded in usable documents. These activities can be carried out by different parties. Therefore, start with the tasks that are necessary and then ask who will take care of them. A job title alone does not indicate which activities are included in a specific quotation.
Architecture and architectural design
The architect or architectural designer works on the spatial and architectural design. Consider layout, shape, use and the coherence of building parts. The exact assignment can vary from an initial design to further development and guidance. The title of architect is protected; If you rely on that title, check the Register of Architects. Be sure to ask about the content, phases and documents of the proposed assignment.
The structural assessment
The structural engineer focuses on the supporting structure and its substantiation. Belastingen, ondersteuning, verbindingen en stability are assessed within the agreed assignment. A spatial wish can therefore have consequences for beams, columns or foundations. Involve this discipline during the design, so that alternatives can be discussed in a timely manner. Ask which existing parts and supplier elaborations will be included.
Architectural and constructive drawings
Een architectural drawing describes other aspects than one construction drawing, although both must refer to the same situation. The architectural draftsman records and further develops the agreed design data. Structural overviews and details must correspond to the calculation. Ask for each document what purpose and level of detail has been agreed. A permit drawing is not automatically a complete production drawing for a supplier.
Who monitors the interfaces?
Openings, steel connections, facade connections and floor heights often affect multiple parties. Record who requests missing information, which party works out the detail and how it is coordinated. Use the same revisions and a document list with open points. This prevents everyone from completing their own part while the connection between those parts has not yet been worked out.
A clear request for design and drawing
Describe your construction goal, the available documents and the support you are looking for. Ask for an overview of phases, results, price and planning. Discuss how many changes or reconciliation are included and how additional work will be agreed. Add the parties involved to the contact list. This creates an assignment that you can compare on content and follow during the project.
Your preparation in four steps
- Wishes, existing situation and design goal
- Required documents per phase
- Division of tasks between disciplines
- Agreements about coordination and revisions
Frequently asked questions on this topic
What does a structural calculation for a new home include?
A related assignment can concern the foundation, floors, walls, columns, beams and roof. The precise parts and drawings must be agreed. Also ask which supplier calculations are required and who monitors mutual coordination.
When do I involve the structural engineer in new construction?
Preferably during the development of the main concept. Large openings, free spans and installation space can affect the supporting structure. Early coordination makes it clear which choices require further research or elaboration before the design becomes final.
View the associated structural calculation, create your preparation list or take the guides and checklists along to the consultation.
